6. Unit internal fuse blown or loose
a. If blown, double-check input voltage and replace fuse.
7. Actual input voltage does not correspond to voltage of unit
a. Verify that the input line voltage is correct. Refer to Section 2, Input Wiring Requirements.
B. Gas flows continuously when power is turned on, AC indicator
flashes
1. Torch switch is activated (closed) before user turns power on.
a. Release torch switch.
2. Faulty torch switch in CNC Control.
a. Check torch switch for continuity. Replace if necessary.
C. Gas flows continuously; Torch will not pilot when torch switch is activated; AC indicator
ON
1. System is in SET mode

E. Torch will not pilot; gas flows; AC indicator
ON, GAS
, TEMP , and DC
indicators OFF
1. Gas pressure is below power supply minimum requirement.
a. Adjust pressure to 65-70 psi / 4.5 - 4.8 bar.
NOTE
Minimum pressure for power supply operation is lower than minimum for torch operation.
F. Torch will not pilot; gas flows; AC
and Gas indicators
ON; DC
and TEMP
indicators OFF
1. Gas pressure is below torch minimum requirement (Minimum pressure for power supply operation is lower than mini-
mum required for torch operation.)
a. Adjust pressure to 65-70 psi / 4.5 - 4.8 bar.
2. Positive and negative wire connections to automation interface PC Board terminals J2-1 and J2-3 are reversed.
a. Check wire connections, correct if necessary.
